Tunneling ionization from the ground state of a Hydrogen atom in an electrostatic (DC) field was solved schematically by Landau, using parabolic coordinates. This provides a simplified physical system that given it proper exponential dependence of the ionization rate on the applied external field. When , the ionization rate for this system is given by: Landau expressed this in atomic units where . In SI units the previous parameters can be expresse…
